Trouble automating login: iface iter could not stat...

[Michael]

I'm trying to implement the automatic login, by doing:
iscsiadm -m node -T <targetname> --op update -n node.startup -v
automatic

When I run this after inserting the proper target name, it seems to
work fine. But when I do: service open-iscsi restart, I get:

Setting up iSCSI targets: iscsiadm: iface iter could not stat /etc/
iscsi/nodes/<target name>/10.3.2.7,3260 (I didn't feel like typing the
whole target name).
iscsiadm: Could not log into all portals. Err 19.

Why can't I log in automatically? When I attempt to log in manually
right after this it works fine:
iscsiadm -m node -T <targetname> -p 10.3.2.7:3260 -l

Anyone know what's going on?

You are root when you do this, right?

And the /etc/iscsi/nodes/<..>/../ does have a default file?

Yes to both questions, Konrad.

What version of open-iscsi are you using? Did it come from
open-iscsi.org or a distro? If it is a distro could you send the
open-iscsi script from /etc/init.d/open-iscsi?

I just tried it real quick with open-iscsi-2.0-869.2 and it worked ok here.

Also after you run the command to set automatic startup could you run:

iscsiadm -m node -L automatic -d 8

and send all the output (the init script should just be doing that
command, so this will dump out a lot of debugging info)?

[Michael]

Ok, I ran the command I previously noted to set automatic startup,
then ran the command you suggested, with this output:

[root@wkstn5 ~]# iscsiadm -m node -L automatic -d 8
iscsiadm: Max file limits 1024 1024

iscsiadm: searching <target name>

iscsiadm: found 10.3.2.7,3260,-1

iscsiadm: iface iter could not stat /etc/iscsi/nodes/<target name>/

10.3.2.7,3260.

iscsiadm: Could not log into all portals. Err 19.

I'm on another computer typing all this manually, so I didn't actually
write the target name here.

Also, it works perfectly fine if I go into /etc/iscsi/nodes/<target
name>/10.3.2.1,3260 and edit the node.startup line myself. Am I just
typing the command wrong without realizing it? Again, I'm doing:

iscsiadm -m node -T <targetname> --op update -n node.startup -v
automatic

What version of the tools are you using and did you upgrade or switch
tool versions?

And did you make this node by hand/manually by doing
iscsiadm -m node -T target -p ip:port --op new
?

The wierd part is that we see this in the log out put you snipped:

iscsiadm: found 10.3.2.7,3260,-1

Here the tpgt is -1 which means it did not get set. Normally targets are
going to send us this so if we did sendtargets we should have that info.

If you do the old style build by hand with no tpgt like this to create
the record:

iscsiadm -m node -T target -p ip:port --op new

then the db uses the old format (so
/etc/iscsi/nodes/<targetname>/10.3.2.1,3260 would be a file)

To use the new format you have to pass in the tpgt

iscsiadm -m node -T target -p ip:port,tpgt --op new

(here there is no /etc/iscsi/nodes/<targetname>/10.3.2.1,3260 file and
we have /etc/iscsi/nodes/<targetname>/10.3.2.1,3260,tpgt as a dir).

> iscsiadm -m node -T <targetname> --op update -n node.startup -v

This is the right command for the new DB format where the tpgt is known
(not -1).

For the old format you had to pass in the target and portal:

iscsiadm -m node -T target -p ip:port --op update -n node.startup -v
automatic

So if you are creating the records manually but do not know the tpgt you
can pass in anything greater than -1 when you create the record, and we
will figure it out dynamically (later to manage the node you would not
pass in anything for the tpgt and we will figure it out or pass in
whatever you passed in when you created it).

iscsiadm -m node -T target -p ip:port,tpgt --op new

Attached is a patch to support the old behavior with new tools. I
thought I added this before, but it looks like for some reason I did not
handle all the cases.

The patch applies to git head or the 869.2.
